蓝光激光二极管平板显示背光模组设计

研制了一款基于蓝光激光二极管的平板显示背光模组，该模组主要包括导光模块以及导光板两部分。研究过程中采用导光模块与导光板分开设计优化的方案，设计了传播过程中横向各部分规则分布、纵向各部分一致分布的一款导光模块以及出光分布均匀的导光板网点，并采用激光打点方式制作出导光板样品。理论模拟得到整个模组的照度均匀度可以达到89.02%，边角平均值可以达到102.74%。实验测量得到照度均匀度可达到79.61%，边角平均值可达到100.10%。该背光模组结构简单，可以为液晶显示提供背光照明。

Abstract

A flat-panel display backlight module based on blue laser diode is designed, which is composed of light guide module and light guide plate (LGP). The scheme of keeping apart the light guide module and LGP is used in the process of designing optimization. A light guide module whose horizontal part distributes regularly, vertical part distributes unanimously in the transmission process and LGP network with uniform output light distribution are designed. The LGP sample is produced by adopting the method of laser dotting. Theoretical simulation shows that the intensity of illumination uniformity can reach 89.02%, and the average value of corner can reach 102.74%, for the whole module. And experiment measurement shows that the intensity of illumination uniformity can reach 79.61%, the average value of corner can reach 100.10%. The structure of this backlight module is simple, and it can offer back lighting for the liquid crystal display.
